Zero-Rated VAT on New Builds — What Trades Need to Know (2026)

The 0% Zero Rate on New Builds

Under VAT Notice 708, the first grant of a major interest in, and the construction of, a new qualifying dwelling is zero-rated. For a builder on the ground, the practical headline is this: when you construct a new dwelling, both your labour and the building materials you supply with that labour can be zero-rated. So a main contractor — or a subcontractor working on the build — invoices the customer at 0% VAT rather than 20%.

Why does this matter so much? Two reasons. First, competitiveness: if you correctly zero-rate a new-build job, your quote is effectively 20% cheaper to a customer who can't recover VAT than a competitor who wrongly adds standard-rate VAT. Second, cashflow: you're not collecting output VAT you'd otherwise hold and hand over to HMRC, while you can still recover the input VAT on your own costs. The zero rate is not "exempt" or "outside the scope" — it's a taxable supply at a 0% rate, which is exactly why your input tax recovery is preserved.

What Counts as a "New Qualifying Dwelling"

The zero rate only applies if the building genuinely qualifies as a new dwelling. HMRC's conditions are specific, and all of them generally need to be met:

• Built from scratch: it's a genuinely new construction, not a conversion or extension of something that already exists. As a rule, any existing building on the site must have been demolished completely to ground level first (a small amount of retained facade kept for planning reasons can be acceptable).
• Self-contained: the dwelling is designed as a single, self-contained living accommodation with its own facilities.
• Lawful planning: the work is carried out in accordance with statutory planning consent and building regulations.
• Separate use and disposal not prohibited: there must be no planning condition or covenant preventing the dwelling from being used or sold or let separately from another property — a common trap with annexes and "granny flats" tied to an existing house.

Crucially, conversions and most works to existing dwellings do not zero-rate. Converting a barn, a pub or a commercial unit into housing, or renovating a house that has stood empty, typically falls under the 5% reduced rate — not the 0% zero rate. If you find yourself working on a building that was already there, default to assuming it is not zero-rated and check the reduced-rate rules instead.

Materials: What You Can and Can't Zero-Rate

On a qualifying new build, "building materials" that you supply and incorporate into the dwelling in the ordinary course of construction can be zero-rated along with your labour. That covers the bricks, timber, plasterboard, roof tiles, wiring, pipework, boilers, fitted kitchen units, sanitaryware and the like — the things ordinarily installed in a home.

But HMRC blocks certain items from zero-rating even on a new build. These stay at 20%, and you cannot recover input VAT on them when you supply them with your construction services. The main blocked categories are:

• Most white goods — free-standing cookers, fridges, freezers, washing machines, dishwashers, tumble dryers.
• Carpets and carpeting material (note: most other floor coverings such as tiles, laminate and engineered wood are not blocked).
• Some electrical appliances and consumer electronics that aren't building materials in the ordinary sense.

The classic pitfall is a fitted kitchen: the units, worktops and sink are building materials and can be zero-rated, but the integrated dishwasher and the cooker are usually blocked white goods at 20%. Split the liability on your invoice so the blocked items are clearly standard-rated.

Certificates and Evidence You Must Hold

For ordinary new-build housing sold or let by a developer, no customer certificate is needed — the qualifying nature of the work is enough. But where the building is for a relevant residential purpose (such as a care home or student accommodation) or a relevant charitable purpose, the customer must issue the contractor a VAT certificate confirming the intended use before you can zero-rate. Don't apply the zero rate on those projects without the certificate in hand.

In every case, the builder must hold evidence that the work qualifies. Keep planning permission documents, drawings, demolition records, the contract and (where relevant) the certificate on file. If HMRC later challenges the liability, the burden is on you to show the zero rate was correct. "The customer told me it was a new build" is not evidence.

How a Subcontractor Treats New-Build Work

This is where many trades get caught out. A subcontractor supplying construction services to a main contractor on a qualifying new build can also zero-rate their work — the zero rate is not limited to the supply to the end customer. So a bricklayer, plasterer, plumber or electrician subbing on a new-build site charges the main contractor 0% VAT on their qualifying construction services.

But the boundaries matter. Some related supplies have their own rules and are not automatically zero-rated even on a new build:

• Professional and architect fees — design, surveying and other professional services are standard-rated at 20%, not zero-rated.
• Scaffolding — the labour to erect and dismantle can be zero-rated as part of construction, but the hire element follows its own treatment; split the invoice accordingly.
• Plant hire — hiring out plant on its own (without an operator and without supplying construction services) is standard-rated.

Get the liability right, because if you under-charge VAT, HMRC assesses the supplier — you — for the tax you should have charged. You may not be able to recover it from your customer after the event, so an incorrect zero rate becomes a cost you absorb. Note too that the domestic reverse charge for construction can apply between VAT-registered subcontractors and contractors, which changes who accounts for the VAT but not the underlying 0% liability.

The DIY Housebuilders Scheme

What about a private individual building their own home? They're not in business and not VAT-registered, so they can't reclaim VAT in the normal way. The DIY Housebuilders Scheme exists to put them in roughly the same position as a developer who buys a zero-rated new build.

Under the scheme, a self-builder can reclaim the VAT they've paid on building materials used to construct their new home. Their builder's labour on a qualifying new build should already be zero-rated, so the reclaim is mainly about the VAT on materials they bought themselves. Claims are now made digitally, and the self-builder generally has up to six months from completion (typically evidenced by the completion certificate) to submit. They'll need invoices and proof of build status. Blocked items — the same white goods and carpets as above — can't be reclaimed under the scheme either. If a self-build client asks you about this, point them at the scheme but don't advise on their personal claim yourself.

Worked Example: £50,000 Job at 0% vs 5% vs 20%

Imagine you quote £50,000 (net of VAT) of construction work. The VAT the customer pays — and the gross they hand over — depends entirely on the correct liability:

• New build (0%): £50,000 + £0 VAT = £50,000 gross. The customer pays no VAT.
• Qualifying renovation/conversion (5%): £50,000 + £2,500 VAT = £52,500 gross.
• Standard-rated work (20%): £50,000 + £10,000 VAT = £60,000 gross.

For a customer who can't recover VAT, that's a £10,000 swing between the zero rate and the standard rate — enough to win or lose the job. The liability isn't a detail; it's the price.

Practical Advice Before You Quote

The liability is a decision you should make before you put a number in front of the customer, not afterwards. A few habits keep you out of trouble:

• Confirm the liability before quoting: establish whether the job is a genuine new build (0%), a qualifying renovation or conversion (5%), or standard work (20%) before you price it. Don't default to 20% out of caution and overprice a zero-rated job — but don't guess at 0% either.
• Keep your evidence: planning consent, drawings, demolition records, the contract and any required VAT certificate. File it with the job so it's there if HMRC asks.
• Split blocked items: show white goods, carpets and other standard-rated items as separate 20% lines on your invoice.
• Get advice on borderline cases: facade retention, annexes with disposal restrictions, mixed new-build-and-conversion projects and relevant residential schemes are exactly where the rules bite. A short conversation with an accountant or VAT specialist is cheap insurance against an assessment.

None of this is tax advice for your specific job — VAT liability turns on the precise facts, and the consequences of getting it wrong land on you as the supplier. When a project sits near the edge of these rules, confirm the treatment before you commit a price.
